Devon wrote the proportional relationship for by markers with the equation y = 3x the variable X represents the number of boxes and the variable y represents the price what are the coordinate points if he bought three boxes of markers

Answer 1

The equation \( y = 3x \) represents a proportional relationship where \( x \) is the number of boxes of markers and \( y \) is the total price.

If Devon bought 3 boxes of markers, you can substitute \( x = 3 \) into the equation to find \( y \):

\[ y = 3(3) = 9 \]

So if \( x = 3 \), then \( y = 9 \).

This gives the coordinate point \( (3, 9) \), which means that if he bought 3 boxes of markers, the price would be $9.

The coordinate points for the scenario where he buys 3 boxes of markers would be \( (3, 9) \).
